Mathematics
1 answer:
Svet_ta [12.7K]1 month ago
4 0

Response:

x equals 7

Step-by-step breakdown:

Information:

∠DEF is 117°

∠DEG measures (12x + 1)°

∠GEF is (5x - 3)°

Objective:

determine the value of x

Calculation:

The equation is ∠DEF = ∠DEG + ∠GEF

117° = (12x + 1)° + (5x - 3)°

117° = 17x - 2

Thus, x = 7

The following bar chart shows the number of different types of animals at two county fairs. Fair X had a total of 645 animals, a
Zina [12379]

Answer:

The proportion of goats at fair Y exceeds that of goats at fair X.

Step-by-step explanation:

From the bar chart,  we see there were 100 goats at both fairs X and Y.

Calculating the percentage of goats at each fair we find:

Fair X = 100/645 * 100 = 15.5%

Fair Y = 100/590 * 100 = 16.9%

This indicates that fair Y had a higher percentage of goats compared to fair X.

Which graph represents a reflection of f(x) = 6(0.5)x across the x-axis?
Inessa [12570]
The blue line depicted in the attached image illustrates the reflection of f(x) across the x-axis. To elucidate, the function f(x) is an exponential function displaying the characteristics: the y-intercept calculates as f(0) = 6(0.5)⁰ = 6; the multiplicative rate of change is 0.5, signifying a decay function (decreasing); and the horizontal asymptote exists at y = 0, defining the limit of f(x) as x approaches positive infinity. The reflection across the x-axis for f(x) results in a function denoted as g(x) = -f(x), leading to g(x) reflecting the features discussed including growth into the third quadrant while never intersecting the x-axis. Therefore, using these insights, it is feasible to sketch the corresponding graph across the x-axis.
